CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of co-pending U.S. application Ser. No. 11/154,749, filed on Jun. 15, 2005, which claims priority to U.S. Provisional Application Ser. No. 60/580,099, filed on Jun. 15, 2004. Priority to the prior applications is expressly claimed, and the disclosures of the applications are hereby incorporated by reference in their entireties and for all purposes.

FIELD

The present disclosure relates generally to portable entertainment systems and more particularly, but not exclusively, to passenger entertainment systems for use in vehicles.

BACKGROUND

Vehicles, such as automobiles and aircraft, often provide entertainment systems to satisfy passenger demand for entertainment during travel.

Conventional passenger entertainment systems include overhead cabin viewing systems and/or seatback viewing systems with individual controls for selecting viewing content. The viewing content typically includes entertainment content, such as audio and/or video materials, and can be derived from a variety of content sources. For instance, prerecorded viewing content, such as motion pictures and music, can be provided by internal content sources, such as audio and video systems, that are installed within the vehicle. External content sources likewise can transmit viewing content, including satellite television programming or satellite radio programming, to the vehicle via wireless communication systems.

Conventional passenger entertainment systems, however, suffer from numerous disadvantages. Some passengers therefore find the passenger entertainment systems to be complicated to operate and the viewing content difficult to enjoy. Selection of the viewing content, for example, can prove difficult due to the awkward placement and operation of the user controls. Similarly, the viewing systems are distally located, such as overhead and/or on an opposing seatback, and typically are not adjacent to the user controls. Also, some or all of the passengers will be inhibited from enjoying the viewing content if one or more viewing systems fails. Such system shortcomings are a frequent source of passenger complaints.

Passenger demand for entertainment likewise is continually evolving. Not only do passengers want to access the most current viewing content, such live television programming and the latest games, but they also require a more extensive selection of entertainment products and services, such as Internet access and in-transit shopping, to be available. Conventional passenger entertainment systems, however, are limited by their fixed hardware technology and cannot easily be adapted to accommodate changing passenger entertainment needs during travel.

In view of the foregoing, a need exists for an improved passenger entertainment system that overcomes the aforementioned obstacles and deficiencies of currently-available passenger entertainment systems.

SUMMARY OF THE PREFERRED EMBODIMENTS

The various embodiments disclosed herein are directed toward portable media devices for presenting viewing content during travel.

The portable media device is configured to communicate with one or more content sources for providing viewing content. Each of the content sources may be proximate to, and/or remote from, the portable media device. Preferably being configured to wirelessly communicate with the content sources, the portable media device can select viewing content from any available content source and can download and present the selected viewing content in any conventional manner. The selected viewing content can be streamed to the portable media device for contemporaneous presentation and/or stored by the portable media device for viewing at any time. As desired, the portable media device can be configured to support two-way communications with one or more of the content sources. The portable media device thereby can provide enhanced functionality, such as support for viewing content uploads and other passenger transactions, during travel.

Preferably being provided in any conventional compressed digital format to facilitate transmission, the viewing content 200 may be provided in any appropriate analog format and/or digital format that may be compressed and/or uncompressed, as desired. To help ensure smooth presentation, the viewing content 200 preferably is buffered when transmitted from the content source 300 to the portable media device 100. The buffering can be provided in any conventional manner, including via, for example, the portable media device 100 and/or the content source 300. When configured to communicate by way of a content distribution system 400 (shown in FIG. 7), the buffering likewise can be associated with the content distribution system 400, as desired.

The viewing content 200, for example, can have entertainment content, including audio content, such as music or audio books, and/or video content, such as motion pictures, television programming, or any other type of audiovisual work. As desired, the viewing content 200 can comprise stored (or time-delayed) viewing content 200 and/or live (or real-time) viewing content 200, such as broadcast transmissions of live events or pre-recorded events. The content source 300 preferably provides the viewing content 200 substantially in real-time. Illustrative formats for the video content can include Audio Video Interleave (AVI) format, Joint Photographic Experts Group (JPEG) format, and Moving Picture Experts Group (MPEG) format; whereas, Waveform (WAV) format and MPEG Audio Layer 3 (MP3) format comprise exemplary formats for the audio content.

Streaming video content preferably is provided in MPEG-4 FGS (Fine Granularity Scalable) format to help ensure transmission efficiency; however, the video content can be streamed by the content source 300 in any suitable standard format. When configured to receive the streaming video content in MPEG-4 FGS format, the portable media device 100 can advantageously maintain compatibility with one or more other video formats, such as other Moving Picture Experts Group (MPEG) formats, including MPEG-1 format and MPEG-2 format. Audio content likewise can be streamed by the content source 300. The streamed audio content can be provided separately, such as with music, and/or in association with other viewing content 200, such as with a soundtrack to a motion picture. Preferably being provided in MPEG-4 BSAC (Bit Slice Arithmetic Coding) format and/or Advanced Audio Coding (AAC) format, the streamed audio content can be streamed by the content source 300 in any suitable standard format.

As desired, other types of viewing content 200, including application software, such as media player programs or games, and/or textual materials, such as forms, reference materials, or other documents, can be provided by the content source 300. Application software typically is provided in an executable (EXE) format, and exemplary formats for the textual viewing content 200 include document text file (DOC) format, Portable Document Format (PDF), and text file (TXT) format. Although selected formats have been discussed above with reference to the audio viewing content 200 and video viewing content 200 for purposes of illustration, the selected formats are merely exemplary and not exhaustive. It is understood that he viewing content 200 thereby can be provided in any suitable conventional format.

The viewing content 200 can be presented by the portable media device 100 in any conventional manner, preferably substantially in real-time. For example, the portable media device 100 can download the viewing content 200 in the manner disclosed in the aforementioned co-pending U.S. patent application, entitled “SYSTEM AND METHOD FOR DOWNLOADING FILES,” Ser. No. 10/772,565, filed on Feb. 4, 2004. As desired, the portable media device 100 likewise can store the downloaded viewing content 200. The portable media device 100 thereby can present the viewing content 200 at any time regardless of whether communication with the content source 300 is maintained.

The viewing content 200 likewise can be streamed to the portable media device 100 from the content source 300. Stated somewhat differently, the viewing content 200 can be momentarily stored (or cached) by the portable media device 100. The viewing content 200 likewise can be streamed in any conventional manner. Content sources 300 for streaming the viewing content 200 can include terrestrial content sources 300 and/or satellite content sources 300. For example, live television programming can be streamed by one or more terrestrial content source 300, such as a broadcast television system (not shown), and/or by one or more satellite content source 300, such as a Direct Broadcast Satellite (DBS) system (not shown). If the portable media device 100 disposed in a vehicle 500 (shown in FIGS. 8A-B) in the discussed below with reference to FIGS. 8A-B, the viewing content 200 can be streamed to the portable media device 100 from a content source 300, such as a media server system 520 (shown in FIGS. 8A-B), installed aboard the vehicle 500.

By streaming the viewing content 200 to the portable media device 100, loss, such as by theft, of the portable media device 100 therefore does not also result in loss of the viewing content 200. To help further ensure the security of the viewing content 200, the viewing content 200 preferably is streamed to the portable media device 100 in an encrypted format and/or can be provided with one or more other digital rights management (DRM) controls. Thereby, the viewing content 200 can be protected against any unauthorized use, copying, and/or dissemination, and/or, even if intercepted or otherwise stolen, the encrypted viewing content 200 will not be readily usable. The viewing content 200 can be encrypted in any conventional manner, including the use of proprietary encryption techniques. By streaming the viewing content 200 from the content source 300, the quantity and complexity of the components comprising the portable media device 100 can be reduced. Thereby, the portable media device 100 can be provided as the portable, handheld media presentation system as discussed above. The weight, complexity, and power consumption of the portable media device 100 likewise can be reduced; whereas, the overall device reliability of the portable media device 100 can be increased.

The viewing content 200, such as stored (or time-delayed) viewing content 200, therefore can advantageously be provided from, or stored in, a central location. Thereby, management of the viewing content 200, including updating the viewing content 200, is facilitated, and the portable media device 100 can present viewing content 200 selected from extensive resources of the content source 300. Further, if the viewing content 200 comprises real-time viewing content 200, including, for example, live satellite television programming, live satellite radio programming, and/or real-time Internet access, the portable media device 100 can present the live viewing content 200 substantially in real-time. The portable media device 100 therefore is not limited to presenting viewing content 200 that can be stored within its resources, which can be limited in comparison with the extensive resources of the content source 300. As a result, the portable media device 100 can be configured to provide a wide variety of viewing content 200 choices, which can be selected and presented on demand.

As illustrated in FIGS. 2A-B, the portable media device 100 preferably can select viewing content 200 provided by the content source 300 and can present the selected viewing content 200 in the manner discussed above with reference to FIG. 1. If the content source 300 is configured to provide a catalogue of available viewing content 200, the portable media device 100 can select relevant viewing content 200 (or selected viewing content 200″), as desired, from the catalogue in any conventional manner. For example, the content source 300 can simultaneously transmit a plurality of viewing content 200 (or aggregate viewing content 200′) from the catalogue as shown in FIG. 2A. The viewing content 200 can be transmitted on a predetermined communication channel and/or can include (or be encoded with) a unique identifier (or address).

The portable media device 100 of FIG. 2A includes a content selection system 150 for receiving the aggregate viewing content 200′ and a content selection signal 250 from the control system 140. Based upon the content selection signal 250, the content selection system 150 thereby can identify the selected viewing content 200″ from the aggregate viewing content 200′, for example, by selecting the predetermined communication channel and/or the unique identifier associated with the selected viewing content 200″. Upon selecting the select the selected viewing content 200″ and, as necessary, providing payment and/or authorization information, the content selection system 150 can provide the selected video content 220 to the video system 120 and/or the selected audio content 230 to the audio system 130 for presentation as discussed above. Although shown and described as being separate from the control system 140 for purposes of illustration, the content selection system 150 can be at least partially integrated with the control system 140, as desired.

Alternatively, or in addition, the content source 300 can transmit the selected viewing content 200″ to the portable media device 100 as shown in FIG. 2B. The portable media device 100 of FIG. 2B is illustrated as being configured to transmit (or upload) upload content 260, including viewing content 200 and/or communication signals, such as the content selection signal 250, to the content source 300. In other words, the portable media device 100 and the content source 300 can engage in two-way communications. Upon receiving the content selection signal 250, the content source 300 can identify the selected viewing content 200″ associated with the content selection signal 250 and transmit the selected viewing content 200″ to the portable media device 100. In the manner discussed above with reference to FIG. 2A, the content source 300 preferably transmits the elected viewing content 200″ on a predetermined communication channel and/or can include (or be encoded with) a unique identifier (or address) associated with the portable media device 100. The portable media device 100 can receive the selected viewing content 200″ and provide the selected video content 220 to the video system 120 and/or the selected audio content 230 to the audio system 130 for presentation as discussed above.

As desired, the portable media device 100 likewise can transmit upload content 260 (shown in FIG. 3B), such as viewing content 200 and/or system communication signals (not shown), to one or more of the content sources 300A-N as set forth above with reference to FIG. 3B. The portable media device 100 can communicate with any suitable number of content sources 300 and thereby can offer enhanced functionality by providing viewing content 200 from the plurality of content sources 300.

Analogously, a plurality of portable media device 100 each can be configured to present viewing content 200 provided by a selected content source 300. As shown in FIG. 6B, the selected content source 300I can provide viewing content 200IA to the portable media device 100A; whereas, the portable media devices 100B-M can receive respectively receive the viewing content 200IB-M. Being proximate to and/or remote from, the selected content source 300I, each of the portable media devices 100A-M can respectively select the desired viewing content 200IA-M from the selected content source 300I for presentation and can present the selected viewing content 200IA-M. One or more of the portable media devices 100A-M can transmit upload content 260 (shown in FIG. 3B), such as viewing content 200 and/or system communication signals (not shown), to the selected content source 300I as set forth above with reference to FIG. 3B.

The viewing content 200IA-M can be substantially uniform, and/or different, among the portable media devices 100A-M. For example, the viewing content 200IA available to the portable media device 100A can be based upon one or more appropriate predetermined criteria, such as a service subscription level. Based upon the service subscription level, one portion of the viewing content 200IA, such as standard viewing content 200, may be free of charge (or included with the service subscription level); whereas, other portions of the viewing content 200IA, such as premium viewing content 200, may be available only for an additional fee. If access to the premium viewing content 200 is desired, transaction information, including payment information, such as a credit card number, and/or authorization information, such as a personal identification number (PIN) or a password, can be provided by the portable media device 100. Preferably, the portable media device 100 includes a peripheral system 180 (shown in FIG. 3B), such as a credit card reader system, to facilitate the transaction and/or the payment in the manner discussed in more detail above with reference to FIG. 3B.

Further details and features relating to the structure, operation, and functionality of the portable media device 100 are disclosed in the co-pending U.S. patent application, entitled “IN-FLIGHT ENTERTAINMENT PASSENGER CONTROL UNIT,” Ser. No. 09/952,629, filed on Sep. 11, 2001, which is assigned to the assignee of the present application and the disclosure of which is hereby incorporated herein by reference in its entirety.

The portable media device 100 and the content source 300 can be configured to communication in any conventional manner, including directly and/or indirectly via one or more wired and/or wireless communication networks (or systems). Turning to FIG. 7, for example, a plurality of portable media devices 100 are shown as communicating with a plurality of content sources 300 via a content distribution system 400. The content distribution system 400 includes a plurality of conventional access points 410 for providing wired and/or wireless access to the content distribution system 400 and/or the content sources 300. As shown in FIG. 7, the content sources 300A-N can access the content distribution system 400 via access points 410A-N; whereas, access points 410A1-M, 410B1-P are configured to provide the portable media devices 100A1-N, 100B1-P with access to the content distribution system 400. The content distribution system 400 thereby can receive viewing content 200 from a preselected content source 300 and can provide the viewing content 200, in whole and/or in part, to one or more predetermined portable media devices 100, as desired. The content distribution system 400 likewise can be configured to receive upload content 260, such as viewing content 200 and/or system communication signals (not shown), provided by a preselected portable media devices 100 in the manner set forth with reference to FIG. 3B and to provide the upload content 260, in whole and/or in part, to one or more predetermined content sources 300.

One or more of the content sources 300A-N can respectively transmit viewing content 200A-N to one or more of the portable media devices 100A1-M, 100B1-M as viewing content 200A1-M, 200B1-M, respectively, via the content distribution system 400. For example, viewing content 200A from the content source 300A can be provided to the content distribution system 400 and respectively distributed among the portable media devices 100A1-M as the viewing content 200A1-M in the manner set forth in more detail above with reference to FIG. 6B. The viewing content 200A1-M each can comprise the viewing content 200A, in whole and/or in part, and can be substantially uniform, and/or different, among the portable media devices 100A1-M. Each of the portable media devices 100A1-M can select the desired viewing content 200 from among the relevant viewing content 200A1-M, respectively, in the manner set forth in more detail above with reference to FIGS. 2A-B. Upon selecting the viewing content 200A1-M, the portable media devices 100A1-M can present the selected viewing content 200A1-M as desired.

Similarly, one or more of the portable media devices 100A1-M, 100B1-M can transmit upload content 260A1-M, 260B1-M to one or more of the content sources 300A-N as upload content 260A-N, respectively, via the content distribution system 400. The upload content 260A2, 260B1, and 260BM, for example, can be provided by the portable media devices 100A2, 100B1, and 100BM to the content distribution system 400 for distribution between the content sources 300B, 300C as the upload content 260B, 260C in the manner set forth in more detail above with reference to FIG. 6A. As discussed above, the upload content 260B, 260C can comprise a combination of one or more of the upload content 260A1-M, 260B1-M, in whole and/or in part, and can be substantially uniform, and/or different, between the content sources 300B, 300C. Each of the portable media devices 100A1-M, 100B1-M therefore can communicate with each of the content sources 300A-N, as desired, via the content distribution system 400.

The content distribution system 400 can be provided as a conventional wired and/or wireless communication network, including a telephone network, a local area network (LAN), a wide area network (WAN), a campus area network (CAN), personal area network (PAN) and/or a wireless local area network (WLAN), of any kind. Exemplary wireless local area networks include wireless fidelity (Wi-Fi) networks in accordance with Institute of Electrical and Electronics Engineers (IEEE) Standard 802.11, Bluetooth networks in accordance with Institute of Electrical and Electronics Engineers (IEEE) Standard 802.15.1, and/or wireless metropolitan-area networks (MANs), which also are known as WiMax Wireless Broadband, in accordance with IEEE Standard 802.16.

Preferably being configured to support high-speed data communications among the portable media devices 100A1-M, 100B1-M and the content sources 300A-N, the content distribution system 400 preferably comprises a high-speed Ethernet network, such as any type of Fast Ethernet (such as 100 Base-X and/or 100 Base-T) communication network and/or Gigabit (such as 1000 Base-X and/or 1000 Base-T) Ethernet communication network, with a typical data transfer rate of at least approximately one hundred megabits per second (100 Mbps). To achieve high data transfer rates in a wireless communications environment, free-space optics (or laser) technology, millimeter wave (or microwave) technology, and/or Ultra-Wideband (UWB) technology can be utilized to communicate with selected portable media devices 100 and/or selected content sources 300, as desired.

The content distribution system 400 likewise can be provided with any appropriate topology, protocol, and/or architecture. Comprising a geometric arrangement of portable media devices 100 and the content sources 300, common network topologies include mesh, star, bus, and ring network topologies. The topology of the content distribution system 400 likewise can comprise a hybrid of the common network topologies, such as a network tree topology. Network protocols define a common set of rules and signals by which the portable media devices 100 and the content sources 300 can communicate via the content distribution system 400. Illustrative types of network protocols include Ethernet and Token-Ring network protocols; whereas, peer-to-peer and client/server network architectures are examples of typical network architectures. It will be appreciated that the network system types, topologies, protocols, and architectures identified above are merely exemplary and not exhaustive.

As shown in FIG. 7, the portable media devices 100 can be separated into two or more device groups 105 based upon any appropriate predetermined criteria. The portable media devices 100 of FIG. 7 are shown as being separated into two device groups 105: first device group 105A; and second device group 105B. If the portable media devices 100 are associated with a vehicle 500 (shown in FIGS. 8A-B), for example, the portable media devices 100 in the first device group 105A can be associated with a first class section of the vehicle 500; whereas, the portable media devices 100 in the second device group 105B can be associated with a coach class section of the vehicle 500. Similarly, the device groups 105A, 105B may be respectively associated with the operator and passengers of the vehicle 500. The functionality of the portable media devices 100 in the first device group 105A can differ from the functionality of the portable media devices 100 in the second device group 105B. For example, the portable media devices 100 in the first device group 105A may be permitted to access premium content that is not available to the portable media devices 100 in the second device group 105B. The portable media devices 100 in the second device group 105B likewise might be required to make payment of a fee prior to permitting access to the content source 200; whereas, the portable media devices 100 in the first device group 105A may not require payment of the fee to access the content source 200.

The portable media devices 100 preferably are configured to communicate. For example, the portable media devices 100 can communicate via the content distribution system 400 such that viewing content 200 can be exchanged among two or more portable media devices 100 during travel. The portable media devices 100 can be configured to communicate with other portable media devices 100 within the same device group 105, and/or portable media devices 100 in different device groups 105 can communicate. Thereby, the upload content 260B2 transmitted by the portable media device 100B2 thereby can be provided as the viewing content 200A1 provided to the portable media device 100A1 and/or as the viewing content 200BP provided to the portable media device 100BP.

As desired, the portable media devices 100 can be initialized in any conventional manner. For example, the portable media devices 100 can be initialized by precharging the battery system 190 (shown in FIG. 4B) of each portable media device 100 to a full charge. The portable media devices 100 likewise can be initially provided with uniform viewing content 200. The uniform viewing content 200 can be provided to the portable media devices 100 in any conventional manner and preferably is stored by the memory systems 144 (shown in FIG. 3B) as stored content 240 (shown in FIG. 3B) in the manner discussed above with reference to FIG. 3B. Each of the portable media devices 100 can receive the same uniform viewing content 200 and/or the uniform viewing content 200 can vary among the device groups 105. The portable media devices 100 within each device group 105 thereby can receive uniform viewing content 200 associated with the relevant device group 105.

Turning to FIGS. 8A-B, the portable media device 100 and the content source 300 can be associated with a vehicle 500 and can form a vehicle information system 510. In the manner set forth in more detail in the co-pending U.S. patent applications, entitled “SYSTEM AND METHOD FOR MANAGING CONTENT ON MOBILE PLATFORMS,” Ser. No. 11/123,327, filed on May 6, 2005, and “SYSTEM AND METHOD FOR PRESENTING HIGH-QUALITY VIDEO TO PASSENGERS ON A MOBILE PLATFORM,” Ser. No. 60/673,171, filed on Apr. 19, 2005, the respective disclosures of which are hereby incorporated herein by reference in their entireties, the vehicle information system 510 can comprise a conventional information system and can be configured to be installed in any suitable type of vehicle 500. Exemplary types of vehicles can include an automobile 500A (shown in FIG. 8A), an aircraft 500B (shown in FIG. 8B), a bus, a recreational vehicle, and/or a boat, without limitation. If installed on an aircraft 500B as illustrated in FIG. 8B, for example, the vehicle information system 510 can comprise a conventional aircraft passenger in-flight entertainment system, such as the Series 2000, 3000, eFX, and/or eX2 in-flight entertainment system as manufactured by Panasonic Avionics Corporation (formerly known as Matsushita Avionics Systems Corporation) of Lake Forest, Calif.

The vehicle information system 510 of FIG. 8A is illustrated as being installed in an automobile 500A and as including a conventional media server system 520. In the manner set forth in more detail above with reference to FIG. 7, the media server system 520 is configured to communicate with one or more portable media devices 100 via a distribution system 400. The media server system 520 thereby can provide viewing content 200 to one or more of the portable media devices 100 as previously discussed with reference to the content source 300. Stated somewhat differently, the media server system 520 of the vehicle information system 510 can function as a content source 300. As desired, the media server system 520 likewise can receive upload content 260 from one or more of the portable media devices 100 as discussed above. By using the portable media devices 100, passengers traveling aboard the automobile 500A therefore can enjoy the viewing content 200 during travel.

As shown in FIG. 8A, the portable media devices 100 can be associated with passenger seats 600 in the automobile 500A. For example, a driver seat 600A is provided with a selected portable media device 100 that is associated with a first device group 105A; whereas, the remaining passenger seats 600B are provided with selected portable media devices 100 that are associated with a second device group 105B. In the manner discussed with regard to FIG. 7, the functionality and/or viewing content associated with the portable media device 100 in the first device group 105A can be substantially the same as, and/or differ from, the functionality and/or viewing content associated with the portable media devices 100 in the second device group 105B. Since the driver needs to pay attention to the road, for instance, the portable media device 100 in the first device group 105A likely does not include a video system 120 (shown in FIG. 3A-B); whereas, the portable media devices 100 in the second device group 105B can include video systems 120. Similarly, the input system 170 (shown in FIGS. 3A-B) for the portable media device 100 in the first device group 105A can be configured to mute the audio systems 130 (shown in FIGS. 3A-B) for each of the portable media devices 100 in the automobile 500A. Advantageously, the portable media devices 100 can present the selected viewing content 200 and/or to provide the upload content 260 without any additional equipment being installed at the passenger seats 600.

FIG. 8B illustrates the vehicle information system 510 as being installed in an aircraft 500B. As shown in FIG. 8B, the vehicle information system 510 includes a media server system 520 and a plurality of portable media devices 100 each being provided in the manner set forth in more detail above. Being disposed within the aircraft 500B, the media server system 520 is configured to function as a content source 300, such as content source 300A, and can communicate with one or more of the portable media devices 100 via a distribution system 400 as discussed above. In the manner set forth with reference to the media server 520 (shown in FIG. 8A), the media server system 520 of FIG. 8B can provide viewing content 200A to one or more of the portable media devices 100 as previously discussed with reference to the content source 300 and can receive upload content 260A from one or more of the portable media devices 100. Passengers traveling aboard the aircraft 500B thereby can enjoy the viewing content 200A provided by the media server system 520 during travel.

The vehicle information system 510 likewise can be configured to communicate with one or more content sources 300, such as a terrestrial content source 300B, that are external to, and/or remote from, the aircraft 500B. The vehicle information system 510 and the terrestrial content source 300B can communicate in any conventional wireless manner, including directly and/or indirectly via an intermediate communication system 560, such as a satellite communication system 560′. As desired, the terrestrial content source 300B can be configured to communicate with, and exchange with viewing content 200 and/or upload content 260 with, other terrestrial content sources (not shown). The terrestrial content source 300B is shown in FIG. 8B as providing access to the Internet 565. Although shown and described as comprising the satellite communication system 560′ for purposes of illustration, it is understood that the communication system 560 can comprise any conventional type of wireless communication system, such as a cellular communication system (not shown) and/or an Aircraft Ground Information System (AGIS) communication system (not shown).

As shown in FIG. 8B, the vehicle information system 510 can include a conventional antenna system 530 and transceiver system 540 for communicating with the terrestrial content source 300B. In the manner discussed in more detail above with reference to the communication interface 160 (shown in FIGS. 3A-B), the antenna system 530 can receive viewing content 200B from the terrestrial content source 300B and provide the received viewing content 200B, as processed by the transceiver system 540, to a computer system 550 of the vehicle information system 510. Being in communication with the content distribution system 400, the computer system 550 can provide the received viewing content 200B to the media server system 520 and/or to one or more of the portable media devices 100, as desired. Although shown and described as being separate systems for purposes of illustration, the computer system 550 and the media server system 520 can be at least partially integrated.

The vehicle information system 510 is shown in FIG. 8B as being configured to transmit upload content 260B to the terrestrial content source 300B. In the manner set forth in more detail above with reference to the communication interface 160 (shown in FIG. 3B), one or more of the portable media devices 100 and/or the media server system 520 can provide upload content 260B to the computer system 550 and provide the upload content 260B, as processed by the transceiver system 540, to the antenna system 530. The antenna system 530 is illustrated as transmitting the upload content 260B to the satellite communication system 560′, which relays the upload content 260B to the terrestrial content source 300B as discussed above. The portable media devices 100 thereby can modify, append, and/or delete content from the terrestrial content source 300B, as desired.

In the manner set forth above with reference to the portable media devices 100 (shown in FIG. 8A), the portable media devices 100 can be associated with passenger seats 600 in the aircraft 500B. Passenger seats 600A are shown as comprising seats reserved for the flight crew; whereas, passenger seats 600B, 600C comprise seats for other passengers, such as travelers. As shown in FIG. 8B, the portable media devices 100 can be separated into three device groups 105A, 105B, and 105C. For example, the passenger seats 600A reserved for the flight crew can be provided with at least one selected portable media device 100 that is associated with a first device group 105A. The remaining passenger seats 600B, 600C are separated into first class passenger seats 600B and coach class passenger seats 600C. The selected portable media devices 100 that are associated with the first class passenger seats 600B are associated with the second device group 105B; whereas, the selected portable media devices 100 that are associated with the coach class passenger seats 600C are associated with the third device group 105C in the manner set forth above.

The functionality and/or the viewing content 200 associated with the portable media devices 100 can be substantially uniform, and/or differ, among the device groups 105A, 105B, and 105C. In the manner set forth above with reference to FIG. 8A, the input system 170 (shown in FIGS. 3A-B) for the portable media devices 100 in the first device group 510A can be configured to mute the audio systems 130 (shown in FIGS. 3A-B) for each of the portable media devices 100 in the aircraft 500B. The functionality and/or the viewing content 200 associated with the portable media devices 100 in the second device group 105B likewise can be substantially uniform with, and/or differ from, the functionality and/or viewing content associated with the portable media devices 100 in the third device group 105C. In the manner discussed above, the portable media devices 100 in the second device group 105B can, for example, access premium content that is not available to the portable media devices 100 in the third device group 105C. The portable media devices 100 in the third device group 105C likewise can require a fee to be paid prior to permitting access to some, or substantially all, of the viewing content 200 available on one or more predetermined content sources 300; whereas, the portable media devices 100 in the second device group 105B may be able to access substantially all of the available viewing content 200 available on the content sources 300 without requiring payment of the fee.

As desired, the portable media devices 100 in one or more selected device groups 105A, 105B, and 105C may be configured to select and present viewing content 200 associated with geography, such as a destination of the vehicle 500 and/or other points of interest, that may, or may not, be related to the travel route of the vehicle 500. For example, passengers can select and view viewing content 200 relating to hotel accommodations and/or a map of the destination city. If the destination is an airport terminal, information, such as arrival and departure times and gate information, for other flights may be provided to assist the passenger with making his connecting flight or with meeting others who are arriving at the airport terminal on different flights.

FIGS. 9A-B provide a view of a passenger cabin 570 of a vehicle 500, such as the automobile 500A (shown in FIG. 8A) and/or the aircraft 500B (shown in FIG. 8B). The passenger cabin 570 is illustrated as including a plurality of passenger seats 600 and at least one access point 410 for access to one or more content sources 300 (shown in FIGS. 8A-B) via the content distribution system 400. Thereby, the portable media devices 100 of FIGS. 9A-B can present selected viewing content 200 from, and/or transmit upload content 260 to, the content sources 300 in the manner discussed in more detail above with reference to FIG. 7. The portable media devices 100 can function to supplement a video presentation system 572, such as an overhead cabin video system 572A and/or seatback viewing systems 572B, and an audio presentation system 574, such as an overhead speaker system 574A, of the vehicle information system 510 as shown in FIG. 9A and/or can be configured to replace the video presentation system 572 and/or an audio presentation system 574 as illustrated in FIG. 9B.

Being provided in the manner discussed in more detail above with reference to FIGS. 3A-B, 4A-D, and 5A-C, the portable media devices 100 are illustrated as including a video system 120, an audio system 130, and an input system 170. Each of the portable media devices 100 likewise includes a communication interface 160 for facilitating communication with at least one of the content sources 300 via a relevant access point 410. The access points 410 of the content distribution system 400 can be distributed throughout the passenger cabin 570 in any suitable manner such that each passenger seat 600 is within a coverage area of at least one access point 410. The entire passenger cabin 570 preferably is within a coverage area of one or more access points 410. Thereby, if the access points 410 comprise wireless access points, the portable media devices 100 can maintain communication with the content sources 300 when the portable media devices 100 are carried about the passenger cabin 570. Stated somewhat differently, the passenger cable 570 can comprise a wireless hot spot, such as wireless fidelity (Wi-Fi) hot spot and/or a Bluetooth hot spot.

Turning to FIG. 9A, for example, each passenger seat 600 is shown as including an individual access point 410. In particular, passenger seat 600W is associated with access point 410W; whereas, passenger seat 600X therefore is associated with access point 410X. The access points 410W, 410X is illustrated as being provided on arm rests 610 of the respective passenger seats 600W, 600×. The access point 410W is a wireless access point that is configured to communicate with a portable media device 100, such as portable media device 100W, that includes a wireless communication interface 160. The portable media device 100X is shown as having a wireless communication interface 160 that is coupled with, and configured to communicate with, the wired access point 410X via a communication cable 580. Although shown and described as being uniformly provided on the arm rests 610 of the passenger seats 600W, 600X for purposes of illustration, the access points 410 can be associated with the passenger seats 600 in any conventional manner, including in a manner that is uniform and/or different among the passenger seats 600.

Access points 410Y, 410Z of FIG. 9B each have coverage areas that include a plurality of passenger seats 600, including passenger seats 600Y, 600Z, respectively. Stated somewhat differently, the passenger cabin 570 and/or the passenger seats 600 can be divided into a plurality of seat zones (not shown) based upon any suitable predetermined criteria. If the seat zones are related to seat class, for example, the passenger seats 600, such as passenger seat 600Y, in a first seat group 605Y can be associated with a first class seat zone (or section) of the vehicle 500; whereas, the passenger seats 600, such as passenger seat 600Z, in a second seat group 605Z can be associated with a coach class seat zone (or section) of the vehicle 500. Therefore, the vehicle information system 510 can provide access to the content sources 300 (shown in FIG. 7) via the access point 410Y to the portable media devices 100, such as portable media device 100Y, that are used in the passenger seats 600, such as passenger seat 600Y, in the first seat group 605Y. Similarly, the portable media devices 100, such as portable media device 100Z, that are used in the passenger seats 600, such as passenger seat 600Z, in the second seat group 605Z receive access via the access point 410Z. The portable media devices 100 thereby can receive viewing content 200 in accordance with the associated seat group 605 in the manner discussed in more detail above with reference to the device groups 105 (shown in FIG. 7).

The passenger seats 600 likewise can provide in-seat power for the portable media devices 100. As shown in FIG. 9B, each passenger seat 500 can include a power port 595 for providing power, having a predetermined voltage level and/or a predetermined current level, that is suitable for the portable media device 100. Preferably being primarily powered by a battery system 190 (shown in FIG. 4B), the portable media devices 100 can receive in-seat power via a power cable 590 that couples the power port 595 with a power port 192 of the portable media device 100. Although shown and described as being provided on the arm rest 610 of the passenger seat 600Z for purposes of illustration, the power port 595 can be associated with the passenger seats 600 in any conventional manner, including in a manner that is uniform and/or different among the passenger seats 600.

The battery system 190 can be periodically replaced and/or recharged as necessary. For example, one or more selected cabin compartments (not shown) in the passenger cabin 570 can be designated for use with the portable media device 100. The cabin compartment can include a battery charging system (not shown) for recharging the battery system 190 of the portable media device 100 during periods of non-use.

Thereby, the selected portable media device 100 can provide one or more predetermined device parameters, including selected identification parameters, such as a device serial number, and/or selected device status (or performance) parameters, such as offload usage statistics, a current content catalogue, an active content catalogue, and/or a current charge level on the battery system 190, to the device management interface 830 in the manner set forth in more detail above with reference to FIG. 12. As set forth above, the device management interface 830 can provide the predetermined device parameters from the selected portable media device 100 to the device management database system 850 as the download management data 842, at 860F.

Upon receiving the download management data 842, the device management database system 850 can update the historical records for the selected portable media device 100 to include the information included in the download management data 842 as discussed above with regard to FIG. 12. The device management database system 850 likewise can provide download management data 842 that can include instructions for configuring the portable media device 100 for future use. At 860G, the device management database system 850 can provide the download management data 842 to the device management interface 830. The device management interface 830, in turn, can configure the selected portable media device 100 in accordance with the instructions associated with the download management data 842. In the manner discussed above, the download management data 842 likewise can include selected media content 200 for updating the content catalogue of the selected portable media device 100, which selected media content 200 can be at least temporarily stored via the interface content source 836.

The device management interface 830 therefore, at 860H, can provide the selected media content 200 to the selected portable media device 100 in accordance with the instructions associated with the download management data 842. In the manner discussed above, the device management interface 830 likewise can update the device identification system 810 by providing the download identification data 822. Upon receiving the selected media content 200 and/or the download identification data 822, the selected portable media device 100 can provide a confirmation of receipt to the device management database system 850, at 860I, in the manner set forth above. The confirmation of receipt can comprise a quality check to validate that the selected portable media device 100 has been loaded with the correct viewing content 200. As discussed above with reference to the predetermined device parameters, the confirmation of receipt likewise can include one or more predetermined device parameters, including selected identification parameters, such as a device serial number, and/or selected device status (or performance) parameters, such as a current content catalogue, an active content catalogue, a current charge level on the battery system 190, and/or a “device ready” status parameter. The device management database system 850 preferably updates the historical record for the portable media device to include at least a portion of the information included with the confirmation of receipt.

Since the confirmation of receipt preferably includes the current charge level on the battery system 190, the device management database system 850, at 860J, can determine whether the battery system 190 of the selected portable media device 100 has received a full charge. If the battery system 190 is not fully charged, the device management database system 850 can permit the battery system 190 to continue to charge, at 860K. The device management database system 850 thereafter can periodically request an updated current charge level on the battery system 190, at 860J, to determine whether the battery system 190 has received a full charge. Once the current charge level on the battery system 190 indicates that the battery system 190 is fully charged, the selected portable media device 100 is ready for future use and, at 860L, can be removed from the device interface docking station 832. At 860M, each portable media device 100 in the set can be processed and prepared for future use in the manner set forth above. Once processing is complete, the set of portable media devices 100 can be provided for use, at 860N, and the process ends at 860O.

FIG. 14 illustrates a device management system 800 for simultaneously processing a plurality of portable media devices 100 in the manner set forth above with reference to FIGS. 13A-B. The device management system 800 is shown as including a plurality of device management interfaces 830 in communication with the device management database system 850. Each device management interface 830 likewise can include a plurality of device interface docking stations 832 for receiving a plurality of portable media devices 100. Thereby, the device management interface 830 can receive device identification data 820 from each relevant portable media device 100 and can transmit the device identification data 820, in whole and/or in part, to the device management database system 850 as management data 840 in the manner discussed above. The device management database system 850 can maintain historical records for each of the portable media devices and can provide configuration instruction for configuring each of the portable media devices for future use in the manner set forth above.

Each the device interface docking station 832 can update the portable media devices 100 in the manner set forth in more detail above with reference to FIGS. 12 and 13A-B. For example, a selected device interface docking station 832, such as device interface docking station 832A, can provide the updated viewing content 200 to the associated portable media devices 100 in a wired manner and/or in a wireless manner as set forth above with reference to FIG. 3A, preferably via high-speed data communications. If the portable media devices 100 receive the updated viewing content 200 via wireless data communications, the updated viewing content 200 can be distributed to one or more of the associated portable media devices 100 in any conventional manner. The selected device interface docking station 832, for instance, can sequentially update the associated portable media devices 100 and/or can update two or more of the associated portable media devices 100 in parallel. In other words, the selected device interface docking station 832 can provide the updated viewing content 200 to the associated portable media devices 100 on a one-by-one basis and/or can multicast the updated viewing content 200 to more than one, preferably all, of the associated portable media devices 100.

Although the device interface docking stations 832 for a selected device management interface 830, such as device management interface 830A, can be configured to process the portable media devices 100 in uniform and/or different manners, the device interface docking stations 832 preferably uniformly process the portable media devices 100. Stated somewhat differently, the portable media devices 100 associated with the selected device management interface 830 preferably are processed in a uniform manner, such that the portable media devices 100 are updated with uniform viewing content 200 and the device identification system 810 are uniformly updated with the device identification data 820. The memory systems 144 (shown in FIG. 13A) of the relevant portable media devices 100 thereby can store the same viewing content 200 (or stored content 240) (shown in FIG. 3B). The portable media devices 100 thereby can be uniformly updated for future use in a more rapid manner.

In the manner discussed in more detail above with reference to FIG. 7, the portable media devices 100 can be separated into two or more device groups 105 (shown in FIG. 7). The device management interfaces 830 therefore may be allocated in accordance with the device groups 105. For example, the device management interface 830A can be configured to process the portable media devices 100 associated with a first device group 105A (shown in FIG. 7); whereas, the portable media devices 100 associated with a second device group 105B (shown in FIG. 7) can be processed by the device management interface 830N. Thereby, the portable media devices 100 in each device group 105 can be simultaneously prepared for future use in a parallel manner.

Advantageously, each device management interface 830A-N is shown as respectively including a separate battery charging system 834A-N, interface content source 836A-N, and/or interface memory system 838A-N. The download management data 842A-N and/or the selected viewing content 200A-N can be locally stored at each device management interface 830A-N via interface content sources 836A-N and/or interface memory systems 838A-N. The device management database system 850 thereby is not required to repeatedly provide the selected viewing content 200A-N to each device management interface 830A-N. Instead, the selected viewing content 200A-N can be locally stored on the relevant interface content source 836A-N. Since the portable media devices 100 preferably are uniform, the power 834A-N provided by the battery charging systems 834A-N preferably is uniform. As desired, the device management database system 850 likewise can provide access to the Internet 565. The device management database system 850 thereby can communicate with one or more other device management database systems 850 and/or a central (or master) device management database system (not shown) for coordinating the historical records maintained by each of the device management database systems.

An illustrative embodiment of a multi-bay docking station 870 for the device management system 800 is shown in FIG. 15A. Receiving input power 872 from an external power source (not shown), the multi-bay docking station 870 includes a switching system 876 and a power supply 878 and is configured to communicate with a server system 874. The server system 874 can comprise a conventional computer server system and, as desired, can at least partially incorporate the interface content source 836 (shown in FIGS. 13A and 14) and/or the interface memory system 838 (shown in FIGS. 13A and 14). The server system 874 preferably can be configured to communicate with a plurality of docking stations 870 in the manner discussed above with reference to FIG. 14. The power supply 878 converts the input power 872 into power, having a predetermined voltage level and/or a predetermined current level, that is suitable for the battery systems 190 (shown in FIG. 4B) of the portable media devices 100.

The switching system 876 facilitates communications between the server system 874 and a plurality of device interface docking stations 832, each provided in the manner set forth in more detail above with reference to FIG. 13A. Preferably comprising a high speed switching system, the switching system 876 can be provided as any conventional type of switching (or routing) system in the manner set forth in the aforementioned co-pending U.S. patent application, entitled “SYSTEM AND METHOD FOR MANAGING CONTENT ON MOBILE PLATFORMS,” Ser. No. 11/123,327, filed on May 6, 2005. If configured to support communications in accordance with the Gigabit (such as 1000 Base-X and/or 1000 Base-T) Ethernet standard, for example, the switching system 876 can negotiate appropriate communication data rates, including ten, one hundred, or one thousand megabits per second (10/100/1000 Mbps), and/or a duplex mode, such as a half duplex mode and/or a full duplex mode.

Thereby, when the plurality of portable media devices 100 is disposed in the device interface docking stations 832, the multi-bay docking station 870 can automatically begin to charge the battery systems 190 of the portable media devices 100. The multi-bay docking station 870 likewise can automatically initiate the download of the device identification data 820 (shown in FIG. 14), the update of the viewing content 200 (shown in FIG. 14), and/or the update of the device identification data 820 in the manner discussed above. The download of the device identification data 820 and the update of the viewing content 200 and the device identification data 820 can be controlled via a software application executed by the server system 874. In the manner discussed above, the server system 874 can provide the updated viewing content 200 to the portable media devices 100 on a one-by-one basis and/or can multicast the updated viewing content 200 to more than one, preferably all, of the associated portable media devices 100. The server system 874 likewise can extract any transaction information, such as credit card information, from the portable media devices 100 and can securely process the transaction information.

The multi-bay docking station 870 preferably provides at least one external indicator system (not shown) for each device interface docking station 832. The external indicator system can, for example, show the status of the relevant battery system 190. In addition to indicating whether the device interface docking station 832 is empty, the external indicator system can indicate whether the relevant battery system 190 is being charged, is fully charged, and/or is bad and requires replacement. A similar indicator system may be provided to indicate the status of the viewing content update and/or the device identification data update for each device interface docking station 832.

As desired, the download of the device identification data 820 and/or the update of the viewing content 200 and/or the device identification data 820 can be performed separately from the charging of the battery systems 190. FIG. 15B illustrates a battery charging station 880 for charging battery systems 190 separately from the portable media devices 100 (shown in FIG. 15A). As desired, the battery charging station 880 likewise can be advantageously applied to charge spare battery systems 190 for the portable media devices 100. The battery charging station 880 is shown as including a plurality of power supply/charging circuit modules 884 each for receiving input power 882 and converting the input power 882 into power, having a predetermined voltage level and/or a predetermined current level, that is suitable for the battery systems 190 as discussed with reference to the power supply 878 (shown in FIG. 15A). Preferably, the battery charging station 880 can rapidly charge the battery systems 190. If the battery systems 190 have an eight hour battery life, for example, the battery charging station 880 can fully charge the battery systems 190 in approximately four to five hours. The battery charging station 880 preferably provides at least one external indicator system (not shown) to indicate the status of each battery system 190 in the manner set forth above.

In a typical application, the device management system 800 can be associated with an airport terminal 900 as illustrated in FIG. 16A. The airport terminal 900 includes a plurality of gates 910, which are divided into gate groups 910A-N. Each gate group 910A-N is associated with a ground support station (service station) 920A-N, respectively, for servicing aircraft 500B, including aircraft 500B with vehicle information systems 510. As illustrated in FIG. 16A, each of the ground support stations 920A-N includes at least one device interface docking station 832A-N for uniformly processing portable media devices 100 in the manner set forth in more detail above with reference to FIGS. 13A-B and 14.

The device management database system 850 is shown as being configured to communicate with the database content source 852 as set forth above and/or a airport terminal network 930 provided in the manner set forth in the aforementioned co-pending U.S. patent application, entitled “SYSTEM AND METHOD FOR MANAGING CONTENT ON MOBILE PLATFORMS,” Ser. No. 11/123,327, filed on May 6, 2005. The device management system 800 thereby can configure the portable media devices 100 to include viewing content 200 from the database content source 852 and/or travel information content 940 from the airport terminal network 930 via the device management interfaces 830A-N in the manner discussed in more detail above. Exemplary travel information content 940 can include any conventional type of information regarding each flight, such as a flight number, an aircraft tail number, gate number, flight departure and arrival time data, and/or passenger data.

Having access to the travel information content 940 from the airport terminal network 930, the device management interface 830A at the ground support station 920A can prepare a first set 100′ of portable media devices 100 for use, for example, on a selected future departing flight. In the manner discussed above, the portable media devices 100 can be configured to include uniform viewing content 200A, and the device management database system 850 can update its records for each portable media device 100 in the first set 100′. The records of the device management database system 850 thereby associate each of the portable media devices 100 in the first set 100′ as identified, for example, by serial number, with the selected future departing flight as identified, for example, by flight number, gate number, and/or aircraft tail number.

Therefore, when the relevant aircraft 500B, such as aircraft 500B′ as shown in FIG. 16A, lands at the airport terminal 900 and arrives at the appropriate gate 910 in the gate group 910A, the ground crew (not shown) can provide the first set 100′ of portable media devices 100 to the aircraft 500B′ and/or can retrieve a second set 100″ of portable media devices 100, which were used during the incoming flight, from the aircraft 500B′. A portable (or handheld) device management interface 830A′ can be provided at the aircraft 500B′ to scan each portable media device 100 in the first set 100′ loaded onto the aircraft 500B′ and/or each portable media device 100 in the second set 100″ retrieved from the aircraft 500B′. By scanning the portable media devices 100 at the aircraft 500B′, the historical records maintained by the device management database system 850 thereby can be updated to reflect that each portable media device 100 in the first set 100′ has been loaded onto the aircraft 500B′ and/or that each portable media device 100 in the second set 100″ has arrived at the airport terminal 900. For quality assurance purposes, the ground crew and a representative from the aircraft 500B each validate the number of portable media devices 100 and electronically sign for delivery and receipt.

The second set 100″ of portable media devices 100 can be processed by the device management interface 830A as set forth above. The device management database system 850 thereby can update the historical records for the second set 100″ of portable media devices 100 to include information regarding the return of the portable media devices 100 to the ground support station 920A and can provide configuration instructions for reconfiguring the portable media devices 100 in the second set 100″, in whole and/or in part, for use on one or more subsequent flight as discussed above. As necessary, the historical records maintained by the device management database system 850 likewise can be updated to reflect any portable media devices 100 in the second set 100″ that were identified as being on the aircraft 500B but that were not scanned when the second set 100″ of the portable media devices 100 was retrieved from the aircraft 500B′. The missing portable media devices 100 in the second set 100″ may not have been retrieved from the aircraft 500B′ for a variety of reasons, including, for example, loss and/or theft. Electronic tracking therefore can facilitate the maintenance of a complete historical record for each portable media device 100. Thereby, the device management system 800 can advantageously provide logistical control and management of the portable media devices 100 and/or can provide the associated data to the operator of the aircraft 500B′.

To simplify chain of custody and to help ensure robust tracking of the portable media devices 100, the portable media devices 100 preferably are disposed within one or more device containers 950 in preparation for delivery to the aircraft 500B′ as illustrated in FIG. 16B. The device containers 950 can be provided in any suitable manner. Preferably, the device containers 950 comprise tamper-evident containers that are appropriately sized for use with a standard aircraft galley cart (not shown), such as a half-size galley cart and/or a full-size galley cart. In other words, the device containers 950 can be provided as sealable containers and/or containers that include at least one security seal to evidence that the device containers 950 have been opened. The device containers 950 preferably are constructed such that the device identification systems 810 of the portable media devices 100 can communicate with a device management interface 830 when the portable media devices 100 are disposed within the sealed device containers 950.

Upon receiving the portable media devices 100 and being sealed, the device containers 950 can include indicia for readily identifying the contents sealed within. For example, a packing list 952 can be provided for identifying the contents of the device containers 950. As desired, a separate packing list 952 can be provided for each device container 950, and/or two or more device containers 950 can share a common packing list 952. The packing list 952 can include content information such as a number of the portable media devices 100 stored within the associated device container 950, a device serial number for each portable media device 100, and/or quality assurance information for each portable media device 100. Exemplary quality assurance information can include information, such as a date, location, and inspector name, related to the inspection and sealing of the associated device container 950. As desired, the packing list 952 likewise can include at least one section for comments, such as comments regarding the portable media devices 100. The comments section, for instance, can be used to identify any portable media devices 100 that have problems and to describe the problems. Information from the packing list 952 preferably can be provided to the device management database system 850 (shown in FIG. 16A) such that the historical record for each portable media device 100 can be updated, as needed.

In a preferred embodiment, each of the device containers 950 can include a container identification system 954. The container identification system 954 can be provided in the manner set for in more detail above with reference to the device identification system 810 (shown in FIG. 12) and can communicate with the device management interface 830 (shown in FIG. 12) and, therefore, the device management database system 850 in the manner discussed above. The container identification system 954 can provide content information, such as the content information discussed above with reference to the packing list 952. Preferably, the content information provided by the container identification system 954 includes a number of the portable media devices 100 stored within the associated device container 950, a device serial number for each portable media device 100, a serial number of the security seal, and/or information regarding the aircraft 500′ to which the device container 950 is to be delivered.

As discussed above, the container identification system 954 can communicate with the device management interface 830 such that the content information can be provided to the device management database system 850, which can update the historical record for each portable media device 100. The container identification system 954 can be scanned by the device management interface 830 at each transfer to provide a chain of custody for the device containers 950 and, therefore, the portable media devices 100. For example, the device management interface 830 can scan the container identification system 954 of outgoing device containers 950 when the device container 950 is inspected and sealed, when the device container 950 leaves the ground support station 920A-N (shown in FIG. 16A), and when the device container 950 is provided to, and disposed aboard, the aircraft 500B′. Similarly, the container identification system 954 of incoming device containers 950 can be scanned by the device management interface 830 when the device container 950 is retrieved from the aircraft 500B′, when the device container 950 arrives at the ground support station 920A-N, and when the device container 950 is opened and inspected. The device management system 800 thereby can monitor transfers of sealed device containers 950 rather than transfers of individual portable media devices 100.

After the device container 950 has been opened, the portable media devices 100 can be inspected for any damage and, as necessary, repaired. The portable media devices 100 then can be coupled with device interface docking station 832 (shown in FIG. 13A). While the battery systems 190 (shown in FIG. 4B) of the portable media devices 100 are being recharged, the device identification data 820 can be downloaded from the device identification systems 810 and provided to the device management database system 850. The device management database system 850 thereby can update the historical records of the portable media devices 100 and can provide configuration instruction for configuring the portable media devices 100 for future use in the manner set forth in more detail above. In accordance with the configuration instruction received from the device management database system 850, the device management interface 830 can configure each portable media device 100, updating the device identification data 820 stored by the device identification system 810 and/or updating the viewing content 200 stored by the memory system 144, as discussed above.

The sealed device containers 950 of portable media devices 100 can be delivered to the aircraft 500B in any conventional manner. As illustrated in FIG. 16B, for example, the first sealed device containers 950′ is illustrated as including the first set 100′ of portable media devices 100 provided in the manner set forth in more detail above with reference to FIG. 16A. The first sealed device containers 950′ can be included in one or more larger flight delivery containers 960, such as first flight delivery containers 960′, with other containers, such as food storage containers 970 for storing meals 972, beverages 974, and/or snacks 976. Similarly, the second set 100″ of portable media devices 100 can be provided as discussed above and can be provided in second sealed device containers 950″ for retrieval from the aircraft 500B′. In the manner set forth above, the second sealed device containers 950″ can be included in one or more larger flight delivery containers 960, such as second flight delivery containers 960″, with other containers, such as a refuse storage container 980. Thereby, the aircraft 500B′ can be prepared for flight by retrieving the second flight delivery container 960″ including items, such as the second set 100″ of portable media devices 100, that were used during prior travel and by providing the first flight delivery container 960′ including items, such as the first set 100′ of portable media devices 100, for use during subsequent travel to the aircraft 500B′. Preferably, a fresh set of portable media devices 100 is provided for each flight of the aircraft 500B′.

In the manner discussed above, the portable media device 100 can be configured to facilitate commercial transactions, including commercial transactions initiated by passengers traveling aboard a vehicle 500 (shown in FIGS. 8A-B). Since commercial transactions typically require payment information, such as a credit card number, and/or authorization information, such as a personal identification number (PIN) or a password, the portable media device 100 includes an input system 170 (shown in FIGS. 3A-B) for entering such transaction information (not shown). The input system 170 can be provided as discussed above with reference to FIGS. 3A-B and typically comprises a keyboard and/or a mouse. Preferably, the portable media device 100 likewise includes a credit card reader system for providing payment information in the manner set forth in more detail above with reference to FIG. 3B.

Illustrative commercial transactions can include transactions for securing access to the portable media device 100 itself. For example, transaction information may be required to rent (and/or activate) the portable media device 100. The portable media device 100 likewise can require transaction information (or additional transaction information) to access selected functions of the portable media device 100, such as to access the viewing content 200 (shown in FIGS. 3A-B) stored on the memory system 144 (shown in FIG. 3B). Access to premium viewing content 200 can require additional transaction information. As discussed in more detail above, the portable media device 100 can store the transaction information on the memory system 144 and/or can transmit the transaction information as the upload content 260 (shown in FIGS. 3A-B). If stored on the memory system 144, the transaction information preferably is uploaded from the portable media device 100 and provided to the device management database system 850 for processing in the manner discussed in more detail above with reference to the device management system 800 (shown in FIGS. 12 and 13A-B).

If disposed on a vehicle 500 (shown in FIGS. 8A-B), such as an aircraft 500B (shown in FIG. 8B), for example, the portable media device 100 can be configured to communicate with a vehicle information system 510 (shown in FIGS. 8A-B) installed on the vehicle 500. Upon receiving the transaction information from the portable media device 100, the vehicle information system 510 can process the transaction information in any conventional manner, such as via a computer system 550 (shown in FIG. 8B) of the vehicle information system 510. For example, the vehicle information system 510 can process the transaction information in real time by instantly downloading the transaction information to a terrestrial payment system (not shown) via a communication system 560 (shown in FIG. 8B), such as a satellite communication system 560′ (shown in FIG. 8B). The vehicle information system 510 likewise can process the transaction information in a time-delayed manner by storing the transaction information for downloading to the terrestrial payment system at a later time, such as arrival the destination of the vehicle 500. To help ensure security, the transaction information preferably is stored and/or transmitted in an encrypted format.

The commercial transactions can comprise any conventional type of commercial transactions, including commercial transactions performed via the Internet 565 (shown in FIG. 8B). In a preferred embodiment, the commercial transactions can include commercial transactions involving merchandise (not shown), such as duty-free merchandise in the case of international travel, and/or services that are available via the vehicle 500. Information regarding the merchandise and/or services can be visually and/or audibly presented via the portable media device 100 and can include textual information and/or graphical information describing the merchandise and/or services. The portable media device 100 likewise can one or more relevant Internet links and/or present various merchandise options, such as available sizes and/or colors, and/or service options. The desired merchandise and/or services can be selected for purchase via the portable media device 100 by entering the transaction information. If stored on the vehicle 500, the merchandise can be made available upon receipt of the transaction information; otherwise, the merchandise can be provided upon arrival at the destination and/or shipped to a selected location.

The portable media device 100 likewise can be configured to present advertisement information for selected products and/or services. Uniform advertisement information can be presented by each portable media device 100, and/or the advertisement information can be selectably presented by the portable media devices 100 based upon any suitable criteria. Preferably, the advertisement information comprises directed advertisement information based, for example, upon a passenger's usage of the portable media device 100. The advertisement information can be visually and/or audibly presented via the portable media device 100 and can include textual information and/or graphical information describing the product and/or service.

In the manner discussed above with reference to the communication system 560 (shown in FIG. 8B), the vehicle information system 510 of the aircraft 500B and the terrestrial content source 300B (shown in FIG. 8B) can communicate in any conventional wireless manner. For example, an Aircraft-Ground Information Services—Cellular Modem (AGIS-CM) system for providing two-way data communications between an XMLRPC server system, such as the server system 520 (shown in FIG. 8B), installed on the aircraft 500B and an Aircraft-Ground Information Services (AGIS) server at a ground station while the aircraft 500B is on the ground. The server on board the aircraft 500B includes a Cabin Memory Extension Unit (CMEU2 (AGIS-Air/AGIS-Link)) hard drive array with a communication port that is coupled with a General Packet Radio Service (GSM/GPRS) cellular transmitter/receiver via an RS-232 connection. After the aircraft 500B lands, the server on board the aircraft 500B is configured to dial a telephone number to contact the ground server. The server on board the aircraft 500B and the ground server then can negotiate to form a communication channel using Internet connectivity in accordance with the XMLRPC protocol. Neither the dialing event nor the negotiation event will be triggered by opening a door to the aircraft 500B.

The servers are configured to exchange data while the aircraft 500B is on the ground, regarding of whether the aircraft 500B is stationary or in motion. The data transferred from the server on board the aircraft 500B comprises operational information regarding an in-flight entertainment (IFE) system that is installed on the aircraft 500B. The operational information can include, for example, passenger usage information as well as information regarding any system failures. The ground server can transfer program content, such as movies or television programs, for display during subsequent flight. Prior to forming the communication channel, both servers can store pending data transfers, which are immediately exchanged once the communication channel has been established. Since the server on board the aircraft 500B can store and transmit the pending data transfers, on-board applications, which generate the pending data transfers, are not individually required to provide a data transfer mechanism.

A communication system for providing two-way communications between a cellular telephone on an aircraft 500B and the public telephone network while the aircraft 500B is in flight. The communication system is mounted in an aircraft 500B and is configured for use with standard cellular telephones used by passengers on the aircraft 500B. Being in wireless communication with the cellular telephones, the communication system includes an internal antenna system for exchanging cellular communication signals with the cellular telephones. The internal antenna system can comprise a plurality of antennas distributed throughout the passenger compartment of the aircraft 500B, such as an antenna disposed at each passenger seat, and is coupled with a central transceiver system.

The central transceiver system is configured to receive outgoing cellular communication signals from the internal antenna system and to convert the outgoing cellular communication signals into outgoing satellite communication signals, which are compatible with satellite communications. Coupled with an external antenna system, the central transceiver system is configured to transmit the outgoing satellite communication signals to a satellite system via the external antenna system. The satellite system, in turn, relays the outgoing satellite communication signals to a terrestrial receiving station that is in communication with the public telephone network. The terrestrial receiving station can convert the outgoing satellite communication signals into outgoing telephone signals, which are compatible with the public telephone network, and provides the outgoing telephone signals to the public telephone network. The central transceiver system likewise can receive incoming satellite communication signals the terrestrial receiving station and convert the incoming satellite communication signals into cellular communication signals via a reverse process. Thereby, passengers can make cellular telephone calls during flight.
